Then, at about 1 minute 20 secs, the pregnant passerby steps in. She says: ‘It’s wrong what you’re doing. You don’t know why people are doing what they’re doing’.

Despite this, she points out, they’re still out there ‘judging and filming’.

She goes on: ‘Many people have been abused. You don’t know what their reason is. This is wrong on so many levels’

She tells them that Kids Company is based just around the corner, where she and her colleagues ‘work with girls that have been abused, molested. But all you keep thinking about is what you think is right.’

She argues that abortion is a personal choice, so ‘for people to be standing outside making women feel guilty’ is ‘so wrong’.

The protesters do not respond.

People have been praising the woman on Twitter for speaking her mind, with some saying they were planning to donate to Kids Company – a charity which provides practical, emotional and educational support to vulnerable inner-city children – on her behalf.

Update: A spokesperson for Abort67, the organisation behind the pro-life protest, told Metro.co.uk: ‘Suggesting that we are harassing and intimidating women when there is no actual harassment or intimidation occurring is misogynistic. It suggests that women are inherently too weak to be fully informed about abortion.

‘Sunny seems to miss the irony of filming us outside the clinic whilst he vilifies us for filming ourselves outside a clinic.

‘We film ourselves because those who support abortion, often lie about the way in which we conduct ourselves or they physically assault us. We have used video evidence to prosecute such individuals,’ they added.

Sunny Hundal told us: ‘I went down there because I’d written about what Abort67 were doing and I wanted to show it on video so it continued the debate on how women are being intimidated by such groups.

‘In the UK we assume abortion rights are safe but the aim of groups like Abort67 and some MPs is to change the debate so they can chip away at those rights. I wanted to highlight that this sort of stuff is going on under our noses.’
